CENTRIFUG-AL DEVICE.

Specification of Letters Patent.

Patented July 20, 1909.

Application filed March 25, 1908. Serial No. 423,164.

To all whom it may comer-it:

Be it known that I, FRANZ HAMPL, a subject of the Emperor of Austria-Hungary, and

resident of Elbe-Teinitz, Austrialdun'gary,

have invented a certain new and useful Centrifugal Device, of which the following is a specification. f

l/Vhen n1other-liquor is obtained from crystals, such as sugar crystals for instance, by centrifugal action, it is necessary to purify the crystals by means of washing liquid or the like and therefore the mother-liquor when discharged is accompanied by liquids of different degrees of pur1ty resulting from the washing operation. The separation of the mother-liquor from the liquid in centrifugal a ara-tus has heretofore been found to be 'di cult because the mother-liquor is discharged very slowly and therefore the liquids discharged immediately following the washing operation are mixed with the mother-liquor under way.

The present invention has for its object a provision of centrifugal apparatus wherein a plurality of movable receivers are arranged around the zone of discharge of the usual drum, the receivers being adapted to be turned toward or away from the drum so as to either receive or deflect the liquids discharged therefrom.

The invention will be more fully described in connection with the accompanying drawing and will be more particularly pointed out and ascertained in and by the appended claims.

In the drawing:Figure 1, is a partial vertical sectional view of a centrifugal apparatus embodying my invention showing the receivers in a position to admit liquids discharged from the drum. Fig. 2 is a sectional view on lines AA of Fig. 1.. Fig. 3 is a view similar to Fig. 1 showing the receivers in a position to deflect the liquid discharging from the drum. Fig. 4 is a sectional view on line BB of Fig. 3. Fig. 5 is a vertical sectional view of one of the receivers detached from the apparatus. Fig. 6 is a plan view thereof. Fig. 7 is a plan view partly in section of the actuating means for the receivers. gig. 8 is a sectional view on line CC of Like characters of reference designate similar arts throughout the different figures of the rawing.

formation.

In the embodiment shown a base a is proceiving the wash water and a closed run-way or tube 6 for receiving the motherdiquor.

"vided and is equipped with a trough g for re The trough g, which is preferably open, is T provided with an outlet at h and the tube or run-way e is provided with an outlet at f and both the trough and run-way are of circular An outer casing is indicated at b and extendsupwardly from the base a and closes the upper portion of the apparatus. A supporting member preferably in the form of a ring 0 is secured at 0 to a part of the casing 1) and is provided with a plurality of deending bearing supports n provided with caring studs 1 the purpose of which will hereinafter more fully appear. A rotatable drum 0 having a perforated peripheralwall is disposed within the casing and is provided with a pocket or receiving peripheral cavity for the material'which is indicated at d. Said drum may be rotated in any convenient manner not shown. Between the drum 0 and the outer casing a plurality of receivers are interposed which preferably surround the drum 0 and farm thereab'out a practically closed walL Said receivers indicated at i and are provided with receiving portions "5 and deflecting portions i and said portions are located within the zone of discharge of the drum 0. Said receiver is preferabiy formed of a tube the receiving pertions t being made accessible to the discharging liquid by cutting away a portion of in a manner to be rotated axially and means 7 are provided whereby single operating member may be employed to change the position of :allof said receivers simultaneously from a receiving to a deflecting position, and vice versa. First referring to the mounting of said receiver the lower ends are preferably rovided with cup-bearings which form the bottom of said receivenff The bearing extensions ]c, depending from the cup p, extend into the tube or run way c and the latter forms a bearing boX by means of which axial rotation may be imparted tofthereceivers i and whereby the same may be held in a given position, with res ect to their lower ends.

vided with heads 1 and in the present embodiment said heads g are provided with axially disposed recesses for receiving the bearing-studs Z and the supports it not only serve to retain the upper end of the receivers i in axial alinement with the lower end but they also serve to support the receivers i.

Means for rotating the receivers '11 consist in part of a circular rack s the teeth of which engage rack studs 1* projecting upwardly from the heads q and said rack s is provided with a segment rack 25 which meshes with a toothed segment u. Said segment a is mounted upon a vertical shaft 22 upon the upper end of which a lever w is secured. The heads g of the receivers 'i are provided with openings y to which the support n proects.

When the mass 0? to be treated or subjected to centrifugal action is disposed in the drum 0 the receivers a) occupy the position shown in Fig. 1, the receiving portion '5 admitting the horizontal ets discharged from the drum and conveying the mother-liquor to the cups p from which it passes through the extensions k to the run-way or tube e from whence it is delivered to the outlet f. Subsequent to the separation of the mother-liquor and prior to the washing operation the handle or lever to is actuated to rotate the receivers t and bring the deflecting portions '5 thereof abreast of the drum 0 as shown in Fig. 3, from which it will be seen the Washing liquid is deflected by the portions i of said receivers into the trough g from whence it flows outwardly to the outer casing. It will be seen that the portions i and i are distinct and separate and that the mother-liquor is never brought into contact with the washing liquid as in either positions of the receivers. The adjacent margins abut as shown in Figs. 2 and 4 so as to form a continuous wall around the drum 0. After the receivers have been turned in the position shown in Fig. 3 the mother-liquor in the portions 'i may slowly descend and continue to discharge through the tube 6 and as the deflecting portions i extend below the cup p it would be impossible for the washing liquid to in any way gain access to the tube 6 or in any way intermingle with the mother-liquor. Furthermore the distinct and independent portions t and protect the mother-liquor and the washing liquid with which the respective portions are moistened so that after the portion i is reversed from a non-acting position to an acting position it is used solely to receive the mother-liquor, the same being true of the portion '5.
